STM32F777__HAL_RCC_TIM5_CLK_ENABLE(); TIM5->PSC = HAL_RCC_GetPCLK1Freq()/1000000 - 1; TIM5->CR1 = TIM_CR1_CEN; cyclecountstart = TIM5->CNT; HAL_Delay(1); cyclecountend = TIM5->CNT; cyclecount = cyclecountend - cyclecountstart;I expect to see cyclec...
I want to read from GPIOB in regular intervals into the RAM. After 8 hours of reading blog posts, examples and trying different things I had no success. I am using STM32Cube to generate code and I am using following code to initiate transfer. So far ...
Im trying to do an ADC led counter, but when i debug my program i see the live expression and i can watch the changes in the potentiometer, but D10,D9,D8 AND D7 are on but with 1.8v, and d5,d4,d3,d2 turn on with 3.3v, the main idea is that when i rot...
I'm having a trouble when using multichannel ADC. In my application there is 2 ADC which contains 7 channels. In ADC Interrupt Callback, I'm pushing the read data to array of 7 elements. But I couldn't see the proper value in proper element of array,...
This compiles with no warnings or errors: char buf[256];uint64_t bignum = 0x123456789;sprintf(buf,"bignum: 0x%016llx, %llu\r\n",bignum,bignum);HAL_UART_Transmit_DMA(&huart1,(uint8_t *)buf, strlen(buf));This comes out the terminal:bignum: 0x0000000000...
I'm using STM32F469 with 2M x 16 x 4banks (16MB) SDRAM.I'm just trying to run FMC_SDRAM sample for STM32469l-EVAL and it seems the first 256 data could write/read successfully.My question is that to access memories in 2 to 4 banks, do I need to send...
Hello everyone,I apply STM32F746BE with externel SDRAM 32MB (MT48LC16M16A2P-75 IT:D) and externel FLASH 16MB (MX25L12845GM2I-10G), Ethernet (LAN8710AI-EZK), LCD.Vector' table is located at 0x20000000. Firmware is runned from externel FLASH 0x90000000...
Hello,i calculate an FFT with the STM32F401RE. It works fine so far. Here are the relevant code snippets:arm_rfft_q31(&S1, (q31_t*)fft_input_buf1, (q31_t*)fft_complex_buf1); //takes about 1760 µs arm_cmplx_mag_q31((q31_t*)fft_complex_buf1, (q31_t*...
