We've been building a PCB with four STM32F091s on each PCB and we've built about 50 units by now (over about 3 years). I have now seen three PCBs where the ADC readings are 'bad' on two of the four micros. By 'bad' I mean conversion values are 30% is...
I have seen an example to create 5v tolerant input on STM32H750, a resistor divider controlled by GPIO. Now I can't find find it when I need it...anyone seen this example and maybe can point it out? I suppose I need a buffer in front to avoind impeda...
Hello everyone,I'm having some throuble in reading the direct analog input on channel PA0_C.In my design I'm using several analog input. They seems to work properly in general and I have a precision more or less as expected. On channel PA0_C, though,...
I thought of using an STM32 to build a device which responds to infrequent pushbutton presses, but should also conserve battery. My initial instinct was to use an STM32L4 in Standby or Shutdown mode, setting the GPIO as external interrupts which woul...
Hello, I am using STM32F429IIT6 board . My board is customized and i have Only 6 pins that are PI1(GPIO_input), PH13(GPIO_Output),PA9(UART_Tx),PA10(UART_Rx),VCC,GND. I want to check data through putty. But i am not able to understand how can i make ...
Hi! We have received STM32L162 MCU in LQFP64 package with device marking that doesn't follow the datasheet. In the datasheet for this part product identification lines should be likeSTM32L162RDT6but on the part we had received it isSTM32L162RDT6So th...
I using STM32CubeIDE and STM32L03.I don't understand how to make a simple sample of a ADC channel (in blocking mode). I had config the Cube to generate a ADC_Init() that contains my 6 Analog In channels. I want to have a function that goes like this...
