I've run into another hurdle I don't seem to be able to solve myself while trying to learn embedded STM32 programming. I have a simple test program that transmits characters over a UART with the RX and TX pins looped together and receives them using ...
I am working on a project wher i am using a LEM brand current transducer the model is HTFS 200, was proposed to measure a 250Amps line, but really i have no idea how to adapt the transducer output to the adc of my board, i would appreciate any suppor...
I m a beginner with the FLash and I struggle to find a solution to write and read in FLASH.I wrote the following program but at the function HAL_FLASH_Program the program goes in HardFault_Handler . Looking inside the HAL_FLASH_Program it is possible...
Hi,The package UFQFPN32 (5x5 mm) have an exposed pad but where is the definition of this Exposed Pad in the datasheet for the STM32F302K8 K Must I connect to the GND or is it not connected or maybe another pin definition ? I can't see in the datashee...
I'm using USART2 on PB3 and PB4 which means setting the AFR bits for those GPIO pins to 7. The CubeMX wizard and HAL GPIO libraries agree with this, but the AFR bits for PB4 stubbornly revert to 0 and my USART wont transmit. What is going on? I've tr...
Hi,I have a new project with STM32G474CE and cant get it start. If I program it with STM32CubeProgrammer it runs the a simple code for led blinking. I checked all VDD,Vref,Vbat pins and all okay. But after powering it off and on again, code gets stuc...
Greetings,I have a board with STM32L151RET6. I can program the controller using st-link, but as soon as i try to enter debug mode it ide says cannot read memory. I am using keil and i am trying to enter debug modue using keil debugger and stlink.I ha...
I am using ADC DMA to read 100 sample from 1 cycle input sine wave whose frequency is 1KHz . When we using ADC to read DMA, the DMA reads ADC continuously until buffer is full. I want the DMA to read and store ADC data in buffer one at a time when it...
Working with a L4R5. I have chained TIM1 & TIM3 to create a 32 bit 1mS counter.Is it possible to reset both counters on an arbitrary 32 bit value?I would like to limit the count to 0x240c_8400; msec in one week.I understand how to reset a timer base...
