Looking for schematic design and firmware programming for a single-cell LiPo fuel gauge. The circuit should use a MAX1704 as per the attached circuit, connected to an ATtiny44 with which the MAX should communicate over SPI. One red LED and 4 green LEDs connected directly to 5 of the ATtiny outputs, and a pushbutton switch on one input. Pressing the pushbutton should show the battery charge status for about 5 seconds, then switch all LEDs off. On power-on the battery charge status should also be shown for 5 seconds.

• The project is to develop a Master/Slave RS-485 based protocol to use with PSoC 1 microcontroller. • The code should be written in C with less use possible of PSoC libraries so it can be easily ported to an another microcontroller. • The code should be divided in functions to be called in the code. • The idea is to make PSoC 1 microcontroller a slave that will respond to requests from a master. The slave will have a serial interrupt on the Rx pin of the bus, will check if the message belongs to him with DestID and respond if necessary. • The communication speed should be 115kbps. The maximum time between each query is 50ms. • The data send will not have more then 8 words (16-bytes). • The CRC should be of the form CRC-16 Modbus type specification which use bit-wise shift and exclusive OR operations. The description of the CRC16 used with Modbus can be found here: http://modbus.org/docs/Modbus_over_serial_line_V1_02.pdf. • A good care should be taken to optimize the CRC16 portion of the code so it can respond quickly. Also the use of a table is prohibited. • The code should be provided so it can be tested with one CY8C29466 as a master and the other CY8C27443 as a slave using MAX485 chip. • The ID of the slave should be automatically read on the microcontroller using 8 inputs port with pull-up resistor. (for example with the use of 8-dip switch) The protocol frame: +---------------+ | SOT | +---------------+ | DestID | +---------------+ | OrigID | +---------------+ | Function | +---------------+ | DatLen | +---------------+ | Data 0 Hi | | Data 0 Lo | | ... | | Data 7 Lo | +---------------+ | CRC16 | +---------------+ | EOT | +---------------+ Code: C Software: PSoC Designer 5.4 Microcontroller: CY8C29466 and CY8C27443 Schedule • Budget: 400-700$. • Delivery: 30 days. I look forward to receiving your proposals.
