Posted on October 16, 2015 at 07:51Hello.I'm trying to use DMA for graphic LCD control on F429(STM32Cube_FW_F4_V1.8.0).LCD spec is 160x128 and color is 16bit(RGB565) and bus type is 8bit parallel.So I'm using FMC to access LCD and now it's working w...
Posted on October 16, 2015 at 07:22Hi, I'm using STM32F407VE as I2c master and STM32F091Cb as I2c slave .In slave i have stop the i2c communication for some certain interval and start again . at that time the communication between the both is not ha...
Posted on October 15, 2015 at 11:52 Hi.I'm using 6MHz external crystal for STM32F0 instead of 8MHz.Following standard setup,i have successfully clocked the APB & AHB at 48MHz via PLL with the following modification on the code pasted below: ...
Posted on October 15, 2015 at 16:34I'm porting SDcard code from FatFS_uSD_FreeRTOS for stm32446_eval in STM32Cube to stm32f4-discovery.Reading blocks seems fine, but writing blocks failed.I debugged with GDB. when write it returned crc failed.here i...
Posted on October 12, 2015 at 23:51I have an Discovery board. It has the provision to pass the UART of the target through the on-board ST-Link. I have searched the literature on the board and the manuals. I havent been able to find how this works. I...
Posted on October 08, 2015 at 21:45I want to create a PWM pass-through program that will read a PWM duty cycle from an RC receiver on a pin (Pulse-width: 1ms-2ms @ 50Hz) and then output that duty cycle on another GPIO Pin at 50Hz. (eventually, the p...
