Introduction 1.1. General Information The hardware and software description in this document is valid for the Application Board HAL-APB V1.x. Fig. 1–1: 1.2. Application Board HAL-APB V1.x Introduction The Application Board HAL-APB V1.x (HAL-APB) is an board for programming the Micronas Hall-effect sensor families with analog and digital output formats. The board is equipped with a Micronas Flash micro controller CDC 3207G. It provides an application software supporting a command interface for the communication with a PC. This allows the implementation of specific PC software for engineering purposes or in-line calibration. The HAL-APB can be ordered with a housing or as a PCB version. In the case of a housing, an additional extension board with two sockets for the connection of up to two Hall sensors (depending on the sensor type) is supplied. Two versions of the Application Board HAL-APB are in use: version 1.3 and the updated version 1.5. Both versions are free to be used in laboratories for engineering purposes. Note: For usage in the production, board version 1.5 is mandatory. 6 Oct. 8, 2012; APN000055_003EN Micronas HAL1820, HAL24xy, HAL28xy, HAL36xy, HAL38xy APPLICATION NOTE Application Board HAL-APB V1.x 1.2.1.

Getting started 2.1. 2.1.1. First Steps Check HAL-APB V1.x – Connect the HAL-APB to the supply voltage. – Check if the power-on self-test was passed successfully. (ERROR LED is switched off after power on. Exception: LIN mode) Board Supply The HAL-APB requires a stabilized power supply. For this purpose, either when using it without housing, the connector X2 (DC jack) or the terminal beneath it can be used. Power-On Self-Test The HAL-APB firmware provides a power-on self-test. The self-test is started after connecting the board supply. During the self-test, the status LEDs including the Error LED, will flash. In case of a detected error, the ERROR LED remains illuminated after the self-test. In LIN mode the ERROR LED is switched on as long as the Vsupply of the sensor is not set to 12 V. 2.1.2. Check Communication with PC and Hall Sensor Connection Connect a Hall sensor with the HAL-APB. (a) directly into the socket HAL 1 or (b) into one of the sockets of the HAL-APB extension board (housing version). Note: For the first communication check, we recommend using the sensor specific Programming Environment LabView software provided by Micronas for the specific HAL sensor. you can also – set up a Hyperterminal connection (see Section 6 on page 18) – switch Vdd on using the “vho1” command (see Section 7.2 on page 21). – try to read out a register (see chapter of the used sensor type).

Board Functions 6.1. Serial Command Interpreter This board provides a serial command interpreter for the interaction with a PC, connected via USB or RS232. The serial communication protocol applies a software handshake: – The PC acts as a master, the HAL-APB V1.x as slave, – The HAL-APB V1.x responds to each master COMMAND frame with a RESPONSE frame. 6.1.1. Serial Interface Configuration When using a hyperterminal communication please set the following parameters. Table 6–8: 6.1.2. parameter settings of serial interface Parameter Value Bits per second 38400 Data bits 8 Parity Even Stop bits 1 Flow control none Definition of the COMMAND Frame The command frame is of variable length. There are basically two types of commands: 1. for board configuration 2. for communication with connected Hall device The command string has to end with (ASCII character 0x0D), optionally with (ASCII characters 0x0D, 0x0A). 6.1.3. Definition of the RESPONSE Frame The response frame consists of 7...10 characters plus 1 finishing :.... ST is non-zero in case of errors (see Table 6–9) 18 Oct. 8, 2012; APN000055_003EN Micronas HAL1820, HAL24xy, HAL28xy, HAL36xy, HAL38xy APPLICATION NOTE Application Board HAL-APB V1.x The Rx-characters contain the received data depending on the command (see devicedependent command lists in section 9, 10,...). 6.1.4. Analog Measurements Its also possible to measure analog voltages, as the HAL_VDD or the HAL_VOUT with the ADC of the HAL-APB. The HAL_OUT is only correctly measurable when HAL_VDD equals 5 V. Example ftvdl0 (set VDD to 5 V) ftana1 (measure HAL_VDD) ftana2 (measure HAL_VOUT) VDD = DATA / 1024 x 3 x 5V VOUT = DATA / 1024 x 5V DATA is measured by ftana command as explained in Table 7–11.

Schedule Tables Different schedule tables allow the use of unconditional frames and diagnostic/configuration frames. It is possible to switch between 4 schedule tables, where tables 1 to 3 handle unconditional frames and table 4 handles configuration frames. The PIDs given in the table are the default settings in the HAL-APB V1.x firmware schedule table settings. The PIDs of the unconditional frames in the schedule tables 1 to 3 can be changed in the test terminal. This can be only done while the corresponding table is not scheduled! The number of response bytes is set to a fixed value for each frame inside a schedule table. If a PID is changed accordingly, this length is applied to the new PID. Changed PIDs are lost after powering off the HAL-APB V1.x. Each schedule table includes only two LIN frames! The scheduling time between frames is set to 20 ms (fixed). Note: To apply more user friendly behavior, especially for the saving of special PID settings, the calling application software should implement the preservation of the PID settings.
