I'm designing an ARM MCU board for a cube satellite. This is the first MCU board I've made and good documentation would be very helpful. What ARM manufacturer or ARM series has the best documentation for beginners?
From my experience: because I was familiar with NXP style of 8051 MCU datasheet before, I could simply read NXP M0 datasheet/users manual and sample code/LPCOpen code, to finish my M0 project development smoothly.
By the way, if you are new to ARM. Perhaps you also need a reference book "The_Definitive_Guide_to_the_ARM_Cortex-M0 (M3)" by Joseph Yiu.
