STEVAL-IPC004V1: handheld point-of-sale (POS)

based on the STM32F1 series

Introduction

This user manual describes the functioning of the handheld point-of-sale system (the

STEVAL-IPC004V1) based on the STM32F1 series.

The system consists of the inbuilt thermal printer, external bar code scanner, memory

interface, LCD display, rechargeable battery supply system and many other features.

This system works like a typical POS. It catches the item information thanks to a USB-based

bar code scanner and after processing the information, adds it to the transaction record.

There are 2 methods of payment: smart card/ magnetic card interface over GPRS or cash

through keypad. The thermal printer prints the sales report and the result is recorded in the

onboard memory. The STEVAL-IPC004V1 operates from a 5 V adaptor, which is connected

to the board through the power jack provided. The system also comes with a PC-based

server application which has various access levels to control the STEVAL-IPC004V1

activities such as registration, the loading of item allotment tables in the internal memory,

and the storage of sales data for future reference. The server keeps sales data in the

database up to 2 months and it also monitors the STEVAL-IPC004V1 health status and

accordingly enables/disables its functioning. For human interaction, there is a keypad with

16 keys allowing a flexible interface. Finally, the system can be customized to include

interfaces such as: smart card, GPRS as per customer requests.
