I am using HAL_I2C_Master_Transmit(). That generally works well. However, I sometimes run into an issue when the slave device is not responding. HAL_I2C_MasterTransmit() obviously returns an error after running into timeout, as it should. But then I ...
Dear STM32 MCUs community,I am currently working on a project with the STM32l452RET6 MCU with a goal to use the SAI peripheral for one-directional single wire communication purposes, so only the "data line" (SD_A or SD_B) will be outputted using the ...
Hello, I used STM32F446 MCU. I'm disconnecting the external RTC crystal. Then I turn the device off and on, but the LSERDY bit does not become zero. What could be the reason for this? Thanks.
I am using a Nx_Webserver application example from STM32H735G-DK modified for STM32H743i-Eval. I have moved the Rx, Tx, NetXPool references to RAM_D2 and I find that I get an error when the linker runs if the RxDecripSection and TxDecripSection name...
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...
