Posted on February 10, 2016 at 16:47hi, I'm using the STM32f407-discovery board example of DMA_FLASH_RAM.I've noticed by using systics for time measurements, that memcpy provides better timing than DMA.for example.I have 16bit array of 64 elements t...
Posted on February 09, 2016 at 14:27I worked out on a library for UART debug and I2C basics to read write registers via I2C..problem now is I read the FIFO but it turns out to be zero..Disabled sleep bit..Fifo Enable Register Set, User Control Regi...
Posted on February 11, 2016 at 05:19I am using STMCube with an STM32F746NG-Discovery kit and the IAR tools. I can build the samples with STMCube and run then but if I use strtod() then the application will crash in:_Stoflt + 0x113__iar_Stodx + 0x39...
Posted on February 10, 2016 at 18:49Dear ST, CubeMx lets me enter user labels. Which is a good feature. However Label starting with digits will fail in compilation proccess. In my case I put ''12V_SENSE'' as on the schematic program. Please check Us...
Posted on February 10, 2016 at 15:02I want to generate a PWM output for a GPIO pin without using Timer as the AF. Is there any other way of accurately doing this? Timers in other modes can be used. Code samples will be helpful. #output #pwm #disc...
