Resolved! Why does RS485 receive last sent char on SMT32H753?
Hello,Iam developing RS485 on STM32H753. I use STM32Cube (*.IOC file) for USART configuration (USART with Hardware Flow Control) and everything works perfectly. But last send char by processor is also received in RX buffer. Does anyone know how to pr...
STM32U585 SPI CRC issue
Hello all,I am currently trying to enable the CRC SPI (CRC-16/CCITT-FALSE) on my project, but I can't make it work. You can found bellow the SPI configuration set on CubeMxHere is the message read back on my logic analyser, in yellow (0x0C52) you'll ...
STM32F303 bypass the lack of DMA trigger via GPIO
I use TIM1 to generate PWM. I want to stop it by the BRK signal. I need to delay the BRK signal so that it works only at the end of the PWM period.The delay will be implemented on TIM3 in OPM mode, and for this I need to synchronize the CNT of both t...
Resolved! Mismatch between HAL and Reference Manual on voltage scale max frequencies
I've noticed that the frequencies written in the reference manual are different from the ones used in the HAL.Is there a good reason they are different? Which ones are correct?I attached a screenshot from page 407 of the reference manual.https://www....
The pwm is generating ramp signals when using sensor with i2c interface
hello everyone, I am trying to combine a H-bridge-based motor controller and a sensor connected by i2c with stm32g032k8txx. They both work when i run on different microcontrollers, but when I combine them, the sensor is working fine but the PWM of th...
stack unwinding during exception
Hi, I am trying to test my fault exceptions. In the event of an exception, I would like to get more information about the problem. In the event of an exception, I am finding the stack pointer and trying to get PC by unwinding the stack. I think the P...
"warning: <elfFile> has a LOAD segment with RWX permissions"
Not really an "ask", but more an FYI...I only just now encountered this and see it's relatively new, relating to binutils 2.39...References:https://www.redhat.com/en/blog/linkers-warnings-about-executable-stacks-and-segments("The executable segment w...
Resolved! STM32G431CBU6 has UART4 !
Hi, as advertisedof course , but no : - no UART4 as the datasheet , page 14/200 (false because UFQFPN48 has 4 more pins than LQFP48 ?)- no UART4 as CubeMx : PC10 and PC11 are present , but no UART4I have got a STM32G431CBU6 from an chinese board make...
Triggering ADC Sampling by Timer Events
Posted on August 29, 2014 at 19:35I am trying to setup ADC sampling that is triggered by a Timer. Essentially I want to setup a 1 kHz timer that will trigger an ADC sample every 1 ms, and use DMA to transfer the sample data. I have all the component...
