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...
There appears to be very long lead times for this product. Any reason and is there any chance it will get better?
I need some guide on how to do the basic master send data to the slave for i2c. The question is, I need to send some data to the slave with address 0x68. Unfortunately, my start condition could not be SET and I do not know why.here is the flow chart ...
Hi.I want to konw what changing to use from stm32h745ii to stm32h755ii in same product line.Are there changing firmware, ..., and start-up code? Thank you.
I am trying to purchase STM32 Nucleo-144 development board with STM32H723ZG MCU, supports Arduino, ST Zio and morpho connectivity - Can anyone help me as to where i can purchase these?
Hi! I have been trying for a while now to get the STM32L432KC to transmit on a CAN bus but to no avail. I have been using a MCP2551 as tranciver and i know it works since i have gotten it to work with a STM32L476 board. The interesting part is that w...
