Everyone,
Which ARM series chips can support touch screen? Cortex A8 is too expensive.
I know that ARM cortex M3 and ARM 9 can do it? Then can the LM3S800 and LM3s9B92 of the M3 series do it?
I want t...
Since 28335 only has two eQEP modules, that is to say, it can only measure the speed of two motors at the same time (measured by the optical encoder disk with AB phase output). But now I need to measu...
TI official website DM8168 and AM3894 use the same EVM. Are the two chips' packages and pin definitions exactly the same and compatible? eeworldpostqq...
1. Problem When developing STM32 with IAR, I found that I could not print floating point numbers by redirecting printf to the serial port. The code is as follows: The output is as follows: It can...[Details]
For STM32, there are two ways to reset the software: 1) Use the official software library The system reset function is directly provided in the stm32f10x_nvic.c file of the official software li...[Details]
CMSIS Driver has similar API functions and similar calling methods. It is a further encapsulation based on the ST HAL library. It is much more convenient and simpler to use and configure than the ST ...[Details]
