Posted on February 07, 2018 at 21:12Hello, I'm just wondering what is the threshold voltage used to determine if an external interrupt due to falling or rising edge should occur. I'm attempting to find it in the datasheet, but unsure at which value ...
Posted on February 07, 2018 at 00:21Hello, I�m trying to get a precise measure with the ADC of the NUCLEO-F103RB but I can�t get a stable result. I measure the internal reference voltage in IN17 of ADC1 but the value is also unstable, so I think the...
Posted on February 05, 2018 at 10:19Hi all,I am trying to implement a measurement system using STM32H7 microcontroller. The ADC used will be LTC2320-14 from Linear Technology. I am trying to find what would be the right pheripherial to control and r...
Posted on February 03, 2017 at 17:20I use NUCLEO-F746 and NUCLEO-767, CubeMX 4.19 with FreeRTOS and LWIP.No Watchdog, enough space for sprintf() stack behaviour and SRAM1 only.DC power comes from a DCDC 24/5V converter, super clean, monitored by Osc...
Posted on October 04, 2017 at 20:09How do I have to configure the linker script file to block the required spacefor Ethernet buffers at 0x24000000?STM32H743 starts with DTCM at 0x20000000, but Ethernet works in 0x24000000 only.I want to use the RAM ...
Posted on January 21, 2018 at 01:31Which step is neccessary to have .data and .bss sections in RAM_D2?If I place them in domain D2, HardFault_Handler() is called. Why?There are known bugs in hal_spi.c - Ethernet works sometimes (if you correct the P...
Posted on August 30, 2017 at 20:32Hi,When using normal transmit on UART i can send a message from a router to a coordinator without no issueHAL_UART_Transmit(&huart2, (uint8_t*)xFrame, sLen,100);, but when i try to send it using HAL_UART_Transmit_DM...

Posted on February 02, 2018 at 20:43I'm trying to configure timer 7 in one-shot mode on the STM32L431 and am having an issue with my timer IRQ triggering as soon as I enable the interrupt. It seems like its preloaded with the period value, however I...
Posted on July 02, 2017 at 19:29 Hello, I'm using stm32f407vgt6 MCU in a control system and I'm facing a strange problem in the reset circuit, when I power on the system it doesn't start until I put a short circuit wire manually between reset pin a...
