Hello my friends,I am trying to setup an I2C slave that is being addressed with a read-request and then answers a fixed number of bytes. I was trying to find out what the XferOptions do, but after I could not find out I went through the HAL-driver co...
Hi everybody,first an apologies for my poor English.I'm using STM32G030K8 in my project and I want to use eeprom emulation to save some parameters. I used the following code, however It didn't work. I spend a lot of time but I can find the problem. v...
In attempting to figure out how to stay in the bootloader loop while exchanging packets with the USB DFU tool I came across as what looks like an unintentionally undeleted line of code.Here is the code:static void OPENBL_USART_Go(void) { uint32_t a...
Hallo everyone,Since some time I struggle to get DMA access working on a STM32H723. I was pointed out this MCU is a complicated beast, but I would at least expect sensible, coherent documentation for it.When I look at page 683, I see:on next pag...
Heyho,so I was just checking the MCO1 output of my STM32H733ZGT6 and found some super jittery 64 MHz with full swing between 0V and 3.3V.Then checked my code and found that I had not set the RCC->CFGR and not even initialized the GPIO.When I actually...
HelloI am looking for an example to get the ADC regular sequence transferred by DMA to memory going.I use TIM15 to trigger the ADC regular sequence, which has four measurements, every 5 milliseconds. When I activate the EOS IRQ and toggle a GPIO I se...
Hi, req is generate sine wave and manage frequency precisely . My design require range 2Hz to 10Hz with for example step 0,002Hz.My idea is one PWM timer for sine with same table for exampel 10bit. Second linked timer for manage one sample time on PW...
Hello, we intend to implement a time-dependent channel change via the operational amplifier in voltage follower mode, as described in AN5306 - Rev 1 Page 31, 5.1. However, when checking the output, there is an unwanted gain (x2) on channel 2. Any ide...
Hello everyone. I am currently working on a bootloader with a STM32H743VGT6.I need to write data on both banks which aren't continuous as you can see below: It was recommended in this topic to use HEX format, but I need to stick to bin files. So my ...
Hey guys.I need to enable/disable the line 14 of the EXTI interrupts multiple times, using HALDo i just use the HAL_NVIC_DisableIRQ HAL_NVIC_EnableIRQ ( and HAL_NVIC_SetPriority whenever i re-enable the line?), providing the correct handle to the a...
