Hi All,So I have trying to get the UART to work for a while and after looking at the lines with scope, I discovered the the uart is twice the Baud rate I programmed it to and I don't know why.So I am running my uC of a 16MHz external crystal dividing...
In the data sheet it states that the ADC current at fs=10Ksps is 16 microAmps. I'm struggling to get the current that low. Even just switching on the ADC and its regulator exceeds that valueMy application has a mode where I need the ADC data passed t...
In a word: I seem to have damaged the flash on an STM32F0 Discovery board by attaching external power.DetailsI had peripherals attached to the STM32F030R8-Discovery board that required more than 100mA @ 3V available from the Discovery's on-board regu...
I try to make two H743 boards communicate each other. The master board sends a chunk (~300Bytes) unregularly and the slave board shall receive it and write it to memory via DMA. Interrupt mode working correctly.DMA Normal mode working correctly.DMA C...
When I upload my code the controller it was working fine for few cycles after that it gets stuck somewhere else and the code is not running. I checked it with the debugging mode in that when I run the code is working fine and when it gets struck I st...
Hi all,I've downloaded X-CUBE-53L1A1 software package and found in its debug configuration SEGGER J-LINK as Debug Probe. I'm using Nucleo F401RE.My question is: Is SEGGER J-LINK distribuited by ST? Or I have to change the probe to ST-Link? Thanks
I have single channel ADC measurements on ADC1 and ADC2 working with an STM32H753IIK.I need to measure VBAT, Tempsensor and VREFINT, which the source code says is ONLY on ADC3.I generated the following init code:void MX_ADC3_Init(void) { ADC_Channe...
I am trying to modify my own I2C driver (I don't use Cube) - to talk to a BQ32000 device - it's a I2C RTC chip.The protocol is shown in the picture below.The protocol to read requires a "restart" after sending the chip's address and sub-address to es...
Posted on September 02, 2014 at 02:20I'm trying to connect from an STM32's FSMC to block-RAM inside an FPGA. Since this type of memory is synchronous, I need to expose the FSMC clock to the FPGA.At the moment I have an STM32F4-Discovery connected to...
Hello,I have an application that reads a couple of ADC channels. each time through the main loop. There's no It's a blocking ADC read so nothing else is going on when I'm reading the 2 channels. For testing purposes I have a 3V battery attached to...
