Mapping assembly code

Posted on July 14, 2016 at 17:27 I'm using an STM32L151 board and I want to know how to map a memory address to its function. For example: LDR.W R0, =0x20002A20 MOVS R2, #4 MOVS R1, #4 STR R1, [R0,#0x14] LDR.W R1, =0x20002224 STR.W R2, ...

STM32L0 complementary PWM

Posted on July 13, 2016 at 14:47Hi everybody, in the datasheet of the STM32L073VB, it says there is no advanced timer with complementary PWM output. Still we need two complementary outputs, very simple without delay function. Is it possible to use a...

USB MSC library - null pointers

Posted on July 11, 2016 at 08:28In the file ''usbh_msc.c'' generated by CubeMX there seem to be various instances of null pointer dereferencing. Many functions begin with this statement: MSC_HandleTypeDef *MSC_Handle =  (MSC_HandleTypeDef *) phost->...
