Hi, I am trying to write an interrupt code to trigger LED(PB14) using user button on my NUCLEO board(PC13). however, as I observed from the debugger, pending bit for line 13 constantly at 1 without pushing the button at all.The EXTI->PR1 = 1<<13 stil...
I use 6 ADCs.I use 3 channels(Ch1, Ch3, Ch13) for ADC1.I use 3 channels(Ch2, Ch4, Ch15) for ADC2.Use DMA1 Channel1, DMA1 Channel2 respectively.DMA1 Channel1 is used by ADC1,Number Of Conversion is 3, Rank 1 = Ch1, Rank 2 = Ch3, Rank3 = Ch13.When usi...
hi i'm trying to use the bme680 but i can't find any library for it ,plus the datasheet is so confusing if you had any luck using it please help thanks in advance
I am using STM32L475 dev board and SIM7600 4g module. I have implemented MQTT communication in this project. I can successfully connect to MQTT broker and also able to receive the data. But the problem is size of data is large (240000 bytes ie 234.37...
I am attempting to write register level code to control the I2C peripheral in an STM32G0x1.My read function is failing because the RXNE bit is never getting set. I believe I have implemented the state machine described in RM0444 (p. 958). Is there ...
I have made a target board using STM32G484VE . I am using 11 ADC pins spread across ADC1 - ADC5. I have introduced a 3.3V Zener BZT52-B3V3 as a protection at all ADC inputs, but all the ADC voltages read 0.6V less from the actual voltage ? Any reason...
Hi,Maybe the TL431 is a voltage reference.
Hi ST community,I'm using a WiFi module, which receives data with SPI. The WiFi module has NORX pin, which indicates whether the module can accept the data or not. The data bits sent when NORX is set to high are discarded. So, when transmitting a SP...
Hello, I am new to the community and to the project I am working on.. I am using a STM32 blue pill board and programming it with a simple code of serial communication :void setup() {Serial1.begin(9600);pinMode(PC13,OUTPUT);}void loop() {Serial1.print...
