Could Simplicity Studio Configurator support C8051F5xx? When I create a new project with C8051F5xx, there is no Configurator GUI.

I found lots of C8051xxx had been NRND, which PN should I use in new design?  

Hi all,

 

As mentioned in the title, I am running into difficulty writing to the ports of my EFM8LB1 (Laser Bee). My goal is to toggle two I/O pins (in this case P1.0 and P1.1) in the main loop of my program. I apologize if a similar question has been asked, but I could not find it in my search. Perhaps because it is too simple a question.

In the InitDevice.c file, I have set both ports to push-pull, set both ports to digital, instructed the XBar to skip both ports,  and told the mask to ignore both ports.

 

I have tried several ways of attacking this problem, so I will list the code for a couple:

 

Method 1:

SI_SBIT(BIT0, SFR_P1, 0);
SI_SBIT(BIT1, SFR_P1, 1);

void main (void)
{
  BIT0 = 0;
  BIT1 = 0;

  while (1){

      BIT0 = 1;
      BIT0 = 0;
      BIT1 = 1;
      BIT1 = 0;
  }
}
 

 

Method 2:

void main (void)
{

  P1 &= 0xFC;

  while (1){

      P1 |= 0x01;
      P1 &= 0xFC;
      P1 |= 0X02;
      P1 &= 0XFC;
  }
}

 

 

When I run the code, both pins remain at high and do not change. 

 

Thanks for any input you can provide!

I am working on a C8051F125 8-bit MCU.

Could the SDA of SMBUS and TX1 of UART1 share the same Port Pin to P0.0 at the different time when I use the crossbar?

 

In the Crossbar, I know the SMBUS is Higher than UART 1 in priority .when I only use SMBUS and UART1 at the same time, can I assign SDA and SCL to P0.2 and  P0.3, and TX1 and RX1 to P0.0 and P0.1?

 

What should I do?

 

Thank you.

Hi -

I'm trying to use the FIFO XRAM memory on the EFM8UB11 as general XRAM.  I would like to just use the Keil C compiler to do this, or I would like an example of how to add inline assembly to do it.  For the other bank of XRAM I just use "xdata" when defining the variable -

uint8_t xdata junkvariable;  

I'm hoping there's an easy way to do this -

Thanks,

Lee

 

I am an engineer and about to start a project that will be using a BGM13S Blue Gecko Bluetooth SiP Module as the main (only) microcontoller.  

For the initial release of the product, BlueTooth will NOT be required.  The Microcontoller will have a fairly simple task of responding to button pushes and adjusting a PWM output.

I have been tasked with writing the software for this initial release.  I may or may not be involved when the product gets updated to include Bluetooth. In order to get a jump on the software development I would like to obtain an evaluation/development board that will at least allow me to familiarize myself with the development environment, Studio 4, etc.  

I have found a couple of development boards, such as the SLEXP8027A and SLWSTK6103A.  I suspect that there are others as well.  Can anyone tell me which development board would be closest to the BGM13S  ?

Thank you

Hi,

I would like to use upper ports (P5-P7) as GPIO on C8051F064.

I turned EMI off on these pins: EMI0CF = 0x10;

Ports are in Push-pull mode (P6MDOUT = 0xFF;)

But P6 = ~P6; does not show the signal at the pins.

Could you please give me a hint how to solve it?

I also tried open drain  mode with 360 Ohm pull-up to 5V, with the same effect.

 

Please send me the Letter of Volatility for 8-Bit USB Debug Adapter part number DEBUGADPTR1-USB.  Thank you!

My email is the following:  John_P_Ludes@raytheon.com 

Could I have an EFM8 sample code with CLI function?

Requirement is accept CLI command from UART, get the data from Timer, ADC, PCA and etc., then feedback the results by UART.

THX a lot.

TLDR : I want to program the EFM8BB1LCK without using the usb plug from the kit. I want to flash/debug it with the USB Debugger Adapter 8 Bit. The goal is to make sure I use the right pins before I order a custom PCB.

 

Once I connect the debugger which is connected to the efm8bb1 LCK I get this message :

C:\SiliconLabs\SimplicityStudio\v4\developer\adapter_packs\inspect_c8051\device8051.exe C:\SiliconLabs\SimplicityStudio\v4\developer\adapter_packs\inspect_c8051\device8051.exe -slist -sn EC3005AC68C -vid 4292 -pid 32836

I removed the F326 jumper :

I also tried to Reset the firmware to make sure it's a 8 bit with this software I found from another thread... still doesn't work :  USB RESET

I though it was my usb debugger adapter so I ordered another one... Still unable to connect to the EFM8BB1

What am I doing wrong?

Greetings,

Per the Sensirion spec for the SHT7X there is an ACK bit which is sent from the sensor to the device by pulling SDA line low when it is ready. The delay can be 10 to 390 ms.

When I poll the SDA line, P1.0, it never shows as HIGH or '1' to the 8051, even though the scope indicates the signal is clearly HIGH. Oddly, the 8051 begins to register that the SDA line is pulled low well before it actually goes low. See the attached figure. Teal color trace is the logic analyzer, red for scope of SDA line.

Relevant code snippets:

// Init:
    P1MDIN |= 0x03; // P1.0-1.1 Inputs
    P1MDOUT = 0x02; // P1.0 SDA Open Drain, P1.1 CLK Push-Pull

// Polling Code:
    while (timeout > 0) {
        Delay(63); // 63 => 1 ms
        timeout--;
        if ((P1 & 0x01) == 0) {
            nsda_count++;
            if (nsda_count > 10) {
                Delay(del*3);
                break;
            }
        }
        if ((P1 & 0x01) == 1) {
            sda_count++;
        }
    }

sda_count and nsda_count are how I tell what the 8051 thinks it is seeing at this step.

 

What is going on here? Is this normal?

Cheers,
Joe

Hi All,

I seem to have either destroyed or bricked the MCU on the EFM8SB2 development board. It is identified when I plug it in but I can't upload code to it.

The energy profiler still works and the debugger seems to respond. Is it possible that the MCU is just bricked and it could be revived? If so, how would I do that?

These dev boards are out of stock at DigiKey.

Thanks in advance,

Rob

你好, 我正在研發一個項目, 在出廠前需要儲存一些數據, 考慮成本和產品尺寸, 用到該芯片其中一個功能, FLASH里设置當作EEPROM用, 但研發途中發現有一定機會率在第一次上電時會有數據丢失, 請問會有人遇過相關情況和如何解決?同時會有silabs 的技術工程可以幫忙解答嗎?謝謝!

 

Hi All, I am developing a product, due to the product size and cost consideration, I use one of the MCU function - EEPROM emulation. but I found that there is a possibility that the data will be lost during the first power-up. could anyone can help it? thanks
