RS232
RS-232 (Recommended Standard - 232) is a telecommunications standard for binary
serial communication between devices.
Most of the times during board bring up rs232 is the mandatory way used to communicate
with your new custom board.
Trego group is very experienced in board bring up and device drivers development.
SPI \ I2C
SPI is a very simple and basically consist only of an 8-bit serial shift register and (for master devices) a programmable shift clock. Typical applications consist of one master device (usually a microcontroller)
and one or multiple slave devices (usually peripheral functions, like A/D, EEPROM, display drivers, etc.).
I2C is more complex than SPI, which results in a larger silicon area and therefore slightly more expensive devices.
I2C was initially specified at a maximum speed of 100kbits/sec. This was later increased to 400kbits/sec and lately some devices started to show up that boast 1Mbits/sec.
SPI has availability of higher speed peripheral devices, SPI devices can reach up to 10Mbits/sec.
Trego has implemented a lot of SPI and i2c drivers on custom boards.
