The ISP download interface does not require any peripheral parts. It uses a double-row 2*5 socket. Since there are no peripheral parts, PB5 (MOSI), PB6 (MISO), PB7 (SCK), and reset pins can still be used normally without being interfered by ISP.
Important note: In actual application, if you want to simplify the parts, you can not solder the 2*5 socket. But it is best to keep this space in PCB design so that the software in the AVR can be upgraded later.

AVR MCU ISP (In-System Programming) and Fuse Repair Method (DebugWIRE)
Parallel programming, the earliest programming method, has the most powerful functions, but requires connecting more pins and usually requires a high voltage of 12V~24V.
To distinguish between them, it is called high voltage parallel programming below.
ISP (In System Programmability) is in-system programming, also k

AVR automotive microcontroller ISP considerations
The isp made a brief summary. Through online programming (the chip is programmed by continuously resetting the chip while the high voltage is converted), the MCU's flash, eeprom, fuse bits, encryption bits, etc. can be modified; the download line supports AVR microcontrollers with a clock above 8kHz and a voltage betw

With the return of the Surge chip, is Xiaomi's self-developed ISP a safe bet or a second choice?
Xiaomi's "Surge" chip, which has been silent for a long time, has finally made new progress. Today (30), the second Xiaomi Spring New Product Conference, although the usual slogan "My heart is surging" was used when introducing the S series SoC, the product released was the Surge C1 - Xiaomi's self-developed image pro
