I have a keil V5.18 with latest pack for STM32L051 (STM32L0xx_DFP 1.5.0), the CMSIS version is 4.5.0.
The goal is to use SPI send out information. I find some source code in CMSIS wiki, and initialize SPI port as:
extern ARM_DRIVER_SPI Driver_SPI0; static ARM_DRIVER_SPI *drv = &Driver_SPI0;
And when I compile it, it gives complain:
.\Objects\spi.axf: Error: L6218E: Undefined symbol Driver_SPI0 (referred from thread_spi.o).
Then I dig into the source code and find another implementation:
extern ARM_DRIVER_SPI CREATE_SYMBOL(Driver_SPI, DRV_SPI); static ARM_DRIVER_SPI *drv = &CREATE_SYMBOL(Driver_SPI, DRV_SPI);
The same complain information.
Guessing its a driver missing, I try to install SPI driver in Run-time environment window. In STM32F1 serials pack, the SPI driver is available but not in STM32L0xx serial.
Then I check CMSIS Driver -> Flash(API) -> AT45DB642D (AT45DB642D Flash, SPI), assuming that this package will help me solve the SPI driver problem, the configure window complain:
require 2.01:CMSIS Driver:SPI Install missing component
Same time I found this doccument: http://www.keil.com/appnotes/files/apnt_266.pdf
Far I think its the company haven't provide driver package for STM32L0xx serial that support SPI.
Am I correct? Or did I miss anything? Awaiting for reply!
