In the electronics industry, DSP high-speed computing is suitable for image and audio compression and encoding and decoding, but not suitable for running interfaces. ARM fills this gap. Therefore, amo...
I believe that those who do embedded development know that non-volatile data storage is usually Flash, but there will usually be data loss. However, I have been thinking about what causes data loss. I...
We know that the general process of uboot starting the kernel is: start.s-->start_armboot-->main_loop-->rum_command-->do_bootm-->do_bootm_liunx But some of the specific details are still not clear. 1....
I would be grateful if the expert can give me some advice! I am using Shengbo's CSD communication card, which has four independent serial ports, which can be set to any of rs232, rs422, and rs485. I h...
From the PIC16F946 datasheet, we know that there are two ways to write values to the LCD for display:
1. Directly write the value to LCDDATA1~LCDDATA23
2. Use disconnect t...[Details]
