I have been trying to use three pots as dials for a guitar effects pedal project. Their purpose is to simply read the voltage from 0 - 3.3V and with some scaling (to turn the raw readings into 0-100 values) in the code to store these 3 values inside ...
I am running a STM32F466RE with no OS, using the STM32CubeIDE. Is there a code profiler, or some other way I can measure how many CPU clock cycles it takes for a certain section of code to execute? I am trying to compare different methods of processi...
The datasheet for the STM32H745xI (doc DS12923 Rev 1) states in the notes to Figure 43 (p 191) that the value for R_ADC can be found in Table 96, but it is not given in Table 96. I also cannot find it elsewhere in the datasheet. Where can the value o...
Hello,I have a working system using an STM32F051K6U6, and the code fits in the first 20K or so. Because of the ongoing shortage of specific parts, we would like to include the '051K6U7, '051K8U6 and '051K8U7 as equivalent parts, since temperature ran...
I am experiencing a vey long external interrupt latency up to 2 microseconds.Clock is internal PLL, 64MHz.void HAL_GPIO_EXTI_Rising_Callback(uint16_t GPIO_Pin){ if (GPIO_Pin == TRIGGER_Pin) { __disable_irq(); LL_GPIO_Reset...
Hello,we're also suffering from the general part shortage and are planning to switch some of the STM32 devices we use to a lower temp grade, as those seem to be better available.I'm trying to figure out what impact the switch from a grade 7 to a grad...
Hi, sir.Before I speak, I'm Korean so English may be wrong.But please help me... (T^T)I am using STM32H743VIT for project. And I want to save Flash memoty to some data.Sometime, It is return HAL_OK. So i can save some data in flash memory.but Most of...
While trying to get a bare metal environment up and running on the STM32G431 i seem to have found a way to brick both a nucleo-64 with an STM32G431RBT6 and a nucleo-32 with an STM32G431KBT6.The first one , i switched on the HSE, waited for it to be r...
Hi, I've been facing some issue using HAL_UART_TRANSMIT. The thing is that I want to send a message when I press a button. My idea is to catch the interrupt of the button and setting a flag, then in main sending the message detecting the flag.The pro...
Hi guys,I am using the STM32H750 and try to reprogram the internal 128KB flash.Please check my code as below :During the programming i got the "PGSERR" randomly , and error code is "0x00040000 "Any comment , thanks HAL_FLASH_Unlock(); __HAL_FLASH_CL...
