Posted on February 07, 2018 at 17:41Hi,We are running a system with a single F7 I2C master and a number of F0 based I2C slaves (currently 4 slaves), each slave is connected to the master via ~0.3m cables. We are using 10-bit addressing.We are seein...
Posted on February 06, 2018 at 14:44Dear,I try to understand CAN filtering mechanism to use it in my application. I understand that it is possible to filtering by ID type, frame type and ID scale.In the case of standard ID, I understand that it's p...
Posted on February 07, 2018 at 21:32The 32L496G-Disco board I have is MB1260B, it is clearly not the board depicted on page 15 of MB1261.pdf. I assume the diagram is the Rev A board.
Posted on February 07, 2018 at 06:10I have been trying to get the USART to work on the stm32f3 discovery for a while without any success. Currently, the TX pin (PA2) is at a constant 3.3V, the RX pin (PA3) is at a constant 0V. I am using an FTDI Bas...
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...
