the "system" is a audio player, decoding (in float) MP3 stream, output on I2S to a DAC;cpu H743 , at 200MHz, i/o by DMA1 , stream coming from ESP8266 wlan radio.system ok, running ...maybe 1..3 hours, then hang up:just now got it first time, still in...
Hi all,I am using stm32L552CE. When I enter stop mode or sleep mode, the current is too high (5mA for stop mode, 18mA for sleep mode). /* Enable PWR clock */ __HAL_RCC_PWR_CLK_ENABLE(); HAL_Delay(5000); printf("Go into stop mode\r\n"); /****** Suspe...
Hi,I have control H-bridge with 4 IGBTs . PWM Topology : Push Pull Mode PWM Frequency : 10KHz to 100KHzDead Time : 2.5usDuty Cycle : 0% to 50%Emergency Stop : 2 Fault Pins for Individual ChannelsHow to achieve below wave with STM32G071 MCU and STM32...
I am using STM32F405 UART5 to receive data using interrupt.I generated base code using STM CubeMX. The problem is when I don't transmit data from UART5 TX, the UART5 receiver works fine. But if I send data from UART5 TX, the first 2-3 bytes voltage d...
I want to create a project using an STM32F7 core, but don't want external memory - the MCU has more than enough memory for one or even two framebuffers in internal RAM. However - STMCube will not allow me to enable the Graphics Framework without FMC...
Have STPM32H7 CPU running in 108 Mhz, and UART1 pull off PLL3 @50 Mhz, set baud rate at 3375000 with 8x oversampling rate.Do see the Tx signal by DMA (303 ns each baud ) out to device and replied with about 302 ns baud, signal is clean on the scope, ...
I have a question about the BOOT pin performance of the STM32G031.In the datasheet says that upon reset, the boot pin (PA13) is established at the beginning as the picture shows. But I wanna know if it is only at the beginning of the reset and then I...
Hello!I use STM32F103 MCU Timer 2 in ecnoder mode. Ticks from an encoder go at approximately 1 MHz, so I use prescaler value 25 to decrease the frequency.Sometimes it works fine, but sometimes timer begins to count encoder ticks at double speed - it ...
It's no secret that there is a worldwide shortage of STM32 MCUs and distributors are not even trying to estimate availability.How is STmicro addressing this?
I need company CMRT v. 6.22.
