I have Keil board, MCBSTM32F400. I want to do SPI communication with it, from a device thru ADC, and pass the data to the controller. Pl mention how can I hook the device to the board?
the device could be potentiometer, pressure or temperature transducer, etc.
My curiosity is that Blinky project has only two files, main.c and Blinky.c. Why build picks so many files to compile and makes hex file more than 32K. Perhaps I am picking something extra from the Pack installer.
About 6 to 8 months ago. Blinky was built right in less than 32K. But Windows on my laptop got corrupted and had to be reinstalled. So I had to install other apps as well.
If you can point out where I am making mistake?
It will only build the files that are actually included in your Project - so we'd need to see your Project.
For a simple blinky, you should probably just need:
compiling stm32f4xx_hal.c...compiling stm32f4xx_hal_cortex.c...compiling stm32f4xx_hal_gpio.c...assembling startup_stm32f407xx.s...compiling stm32f4xx_hal_rcc_ex.c...compiling stm32f4xx_hal_rcc.c...compiling system_stm32f4xx.c...
You shouldn't need:
compiling EventRecorder.c...compiling stm32f4xx_hal_adc.c...compiling stm32f4xx_hal_adc_ex.c...compiling stm32f4xx_hal_dma.c...compiling stm32f4xx_hal_dma_ex.c...compiling stm32f4xx_hal_pwr.c...compiling stm32f4xx_hal_pwr_ex.c...
Should I use IDE uVision or IAR for working on the board?
You're seriously asking that in the Keil forum ?!
Hi Andy, As per your last response, I am providing Paint files having list of files in blinky project and the compile error I am getting are attached. I have LIte version. I am not getting file size error more than 32K, but a compile error. If I comment out line 157 in main.c, then I get other errors.
Sounds like you really need to start here:
