Index of /elektro/EPE/2004. MAX232. RS232C Level Converter Wichit Sirichote, kswichit@kmitl.ac.th A standard serial interfacing for PC, RS232C, requires negative logic, i.e., logic '1' is -3V to -12V and logic '0' is +3V to +12V. To convert a TTL logic, say, TxD and RxD pins of the uC chips, thus need a converter chip. A MAX232 chip has long been using in many uC boards. It provides 2-channel RS232C port and requires external 10uF capacitors. Carefully check the polarity of capacitor when soldering the board. A DS275, however, no need external capacitor and smaller.

Hello! You need an application to track where your son goes with your car? You came to the right place. Today, I will just add a report I wrote last year about a GPS module I had put on one of the earliest versions of Soroban. This morning, I set this module on the latest version, compiled, and it just works. The module This is a GPS module with a patch antenna. Now here is a view of its thickness, a little bit under 9mm. The platformThis time (surprise?)
Wiring the module on Soroban Before wiring, I had to punch a hole to leave some room for the 3 antenna pins that are off-pitch. Wiring the module is extremely easy. SoftwareThe software part is quite easy. UART source codeHere is the .h file: (types.h defines uint8, uint16, etc...) Code: Select all #ifndef _USART_H_#define _USART_H_#include <msp430x16x.h>#include "types.h" // Non-realtime functions. // Realtime functions (USART0 send and receive functions) #endif #include <msp430x16x.h>#include "USART.h"#include "globals.h" That's it. Conclusion. Microcontroller and DSP technology.
