Posted on September 23, 2016 at 20:24I am observing an odd behavior with HAL_FLASHEx_Erase. When called to erase multiple pages, the function waits until all pages have been erased before calling FLASH_FlushCaches. I have observed that my simple S...
Posted on December 22, 2016 at 14:14Hi. I'm trying to remap a gpio pin from out to it but the following lines of code don't work.Can someone help me?I need to remap GPIOx, GPIO_Pin from out to in on the fly.void DigitalInOut::SwitchToInput() { HA...
Posted on January 03, 2017 at 09:44I am trying to communicate with a device (a radio module which has inside STM32F103 MCU ) with my STM32f072B disco board using SPI I can program the radio module almost as a standard STM32 MCU the only difference i...
Posted on January 03, 2017 at 10:16Hello All,We are interfacing the OV5642 camera module with STM32f4 discovery board.We are read the camera model no using the i2c protocol. When we are put the break point in the I2C stop condition, we can read the ...
Posted on January 02, 2017 at 19:16I was wondering if I am able to connect an external voltage reference of 4.096 volts to VDDA (to be used as a voltage reference for ADC) without damaging the board?
Posted on January 02, 2017 at 13:31We are using I2C1 in STM32L486 and occasionally we are seeing timeout while calling HAL_I2C_IsDeviceReady,this we are calling before call to HAL_I2C_Master_Transmit_ITThis is happening when USART0 is in use and dat...
Posted on January 02, 2017 at 05:45Hello all,Finally got my ethernet working on my omliex stm32-e407 board though generating code with the STM32Cube.Its responding to pings so good to know that and dhcp are working finally. But it seems the host nam...
Posted on October 03, 2016 at 22:01Is it possible to generate a project in STM32CubeMX to use a USART on STM32F7 parts in RS485 mode? I see RS485 mode listed in the HAL reference and STM32F7 reference, but I can't find details on what pin is used fo...
Posted on September 17, 2016 at 00:56Hi,I used to work on STM32F4 and now are evaluating STM32F7. When I tried to create a project with STM32F769NI with SPI. I found that I can't set the Prescaler to 2 (APB2 = 108Mhz) which will result the SPI6 to 5...
Posted on December 15, 2016 at 20:24The Discovery STM32469I advertises that it comes with 16mb of ram. However, the discovery firmware only enables 11 bits so it only sees 8mb.You can change line 168 to this and it will fix it //sdramHandle.Init...
