STM32U0 is the first Cortex-M0+ with a static consumption of only 160 nA in standby mode with RTC (Real-Time Clock) and 16 nA in shutdown. It also achieves 118 points in CoreMark and targets SESIP level 3 and PSA level 1 focusing on firmware code pro...
Is there a way to make STM32Cube Programmer controls a pair of pins in a CH340 or similar USB to TTL converter, to be able to control BOOT0 and NRST pins of an StM32 micro? I would like to make a simple circuit that permits entering and exiting a bo...
Currently try to configurate settings for register I2C_CRI. Not sure which value should I set for bit NOSTRETCH. I am using I2C as master. This bit only effected when using I2C as slave. But in manual mention must kept cleared in master mode. Meanin...
Hi,This is the first time I am starting a post, sorry in advance if it's not in the correct place.I have a Blue-Pill with original STM32F103C8T6. I have Vbat hooked up to a 0.33 F super cap via 100 ohm. Vdd is connected to V bat with a BAT54C Schottk...
Hi all, i am trying to use MDMA to transfer data from a cyclic ADC-DMA buffermy ADC buffer is of x size and it is cyclic: adc_buffer[x]and i want to transfer its data via MDMA to a larger buffer while its samplingmeaning that after every ADC iteratio...
안녕.최근에 STM32H753XI를 사용하여 맞춤형 보드를 만들었습니다.보드의 초기 테스트를 위해 각 주변 장치에 대한 테스트를 실행하고 있습니다. 대부분의 경우 잘 작동하지만 SD 및 eMMC 사용에 문제가 있습니다.내 보드에는 SD 슬롯 1개와 eMMC가 포함되어 있습니다.eMMC는 SDMMC1에 연결되고 SD는 SDMMC2에 연결됩니다.그리고 둘 다 FatFS에 연결하여 파일 시스템으로 사용합니다.둘 다 각각 사용할 때 매우 잘 작동합니다...
This is more a bug report, not a question.Background:I want to use OCTALSPI as QuadSPI (QSPI), esp. with VDD set to 1V8. I want to get (at least) 30 MHz SCLK working on QSPI.But I cannot go faster as 12.195 MHz, which is associated with a OCTALSPI cl...
Hi, I would like to migrate a code on STM32F271 to a chip STM32H723 while using IAR EW 8.50.xMy problem is that H723 is not in the target list for IAR EW 8.50.5I can target H723 with IAR EW 9.20 but in that way I loose compatibility with other softw...
In Figure 1 of the reference manual RM0433 for the STM32H743 (and STM32H742, STM32H753, STM32H750) no connection between cache and DTCM-RAM exists. For all I know this is correct since the DTCM-RAM is not cachable.Table 7 on the other hand shows tha...
I am attempting to bring up a custom board using a STM32U5A9 chip. I modeled the board off of the STM32u5a9j-dk dev kit (the one with a circular screen). I've been able to get our LCD screen to work over DSI and touchGFX currently runs fine.Now I am ...
