What is the minimum and maximum current that can be applied to an analog input destined for the ADC?
I have some passive input conditioning circuitry that may reduce the curent to an unacceptably low level. There isn't much said about input pin current requirements in the data sheet.
My chip is C8051F320.
I use PCA to measure frequency (15K~5K) and send to PC by USB as 1K speed.
I use interrupt as follow:
3.Timer0 as basetime for PCA
4.Timer1 as 1K to send data to PC
if PCA>USB windows can't find the chip.
if PCA<USB when USB working PCA will timeout then get wrong data.
Hello everyone, I need your valuable ideas ..
We create the usb keyboard based your mouse example with 8051f320. It works with some laptops but with some does not.
I do not understand the real problem. When I check with usb tool when problem happen it says string descriptors are not available(you can find it in the attachment). But sometimes as I said it works perfectly.
I will share the whole code. Can you check it ?
The EFM8SB1-RM.pdf the use of the lock byte but it contadicts the FLASH_PageErase() software
* @fn FLASH_PageErase * * @brief * This routine erases the flash page containing the linear flash address * <addr>. Note that the page of flash page containing the Lock Byte cannot be * erased if the Lock Byte is set. * * @param addr - address of any byte in the page to erase * valid range is from 0x0000 to 0x1FFF for 8 kB devices * valid range is from 0x0000 to 0x0FFF for 4 kB devices * valid range is from 0x0000 to 0x07FF for 2 kB devices * * @return void
Hi, I'm a beginner trying to connect a UB1 microcontroller to a TI drv8830 motor driver via I2C using the SMB bis on UB1. I'm using the starter kit example code Master SMB BUS and code from an141.pdf.
Where are global variable headers like SMB_DATA_OUT and TARGET initially defined? I can't find where they are connected to the smb registers in any of the headers.
Just purchased the starter kit and freshly installed Simplicity Studio with Simplicity IDE (Not Keil).
Have fallen at the first hurdle...
Studio recognises the starter kit and gives me demo options. If I select Rainbow Blinky, I get an error - "Unable to connect to device 000440088718" during 'Uploading to Device'.
I can't understand why there might be a problem uploading, when it clearly is communicating via the USB port (Win 10 and no reported issues in Device Manager).
Possibly associated problem:
If I go to software examples and select the Blink ASM example, it fails in the CDT Build Console: 'Error: Program "make" not found in PATH'.
In the Project Explorer window, there are frequent declarations of 'No Toolchain...etc').
What is a CDT?
What is a toolchain?
