Posted on April 10, 2018 at 05:58Hi,Now I am using STM32F769NI Discovery Board. The board uses MX25L51245GZ2I-10G chip and I can't buy this chip for prototyping.Please advise me a direct replacement chip so that I don't need to change the code.Thank...
Hello,I am working on a code that uses the HAL library for SPI communication. But I have a problem with SPI's state-checking routine.void libera_escrita(void){ SPI_TxBuffer[0] = 6; HAL_GPIO_WritePin(GPIOC, CS_Pin, GPIO_PIN_RESET); while (HAL_SPI_GetS...
I have used Keil for some time, and recently managed to use the LL drivers (much like the old SPL). Recent installation of Keil DID NOT SHOW the STCubeMX options in the RTE configuration window, and I don't know how to get them back.Can anyone help?
Hi,I am experiencing some strange behavior when using the QSPI module to communicate with an Adesto Flash chip. I am using the newest version of the ST HAL driver library.During the Dummy Cycles Phase, the SI pin is transmitting data. This is data is...
I am trying to use FLASH to emulate EEPROM on stm32F767 based on AN3969. My FLASH is organised as a single bank, so executing from FLASH I would expect execution to stall while writing / erasing. The longest stall is when erasing a sector, which migh...
I am trying to port the octoWS2811 for STM32F103c8T6.This guy hubmartin has already done the heavy lifting and created a library using STM32 HAL. But the problem is that i am unable to get it to work. I am using Eclipse IDE.This is his website where ...
Hello everyone.I'm studying in STM32F4 and learn DMA module using Example code of St. The example show how to use DMA in Burst feature to do 3 transfers into timer register beginning at TIMx_ARR after DMA update request.But I don't understand why add...
Posted on July 15, 2018 at 09:26Hi,SBSFU gives me the warning 'SECURE ENGINE INITIALIZATION WITH FACTORY DEFAULT VALUES' on every new power-up of the microcontroller. Is this behavior normal after a power-cycle or is anything not configure correctly...
Hello,I am working on Power Reduction and we are using STM32F446RE Microcontroller. In the RM i found this, "the regulator output voltage (around1.2 V) can be scaled by software to different voltage values (scale 1, scale 2, and scale3 can be configu...
