The full VB executable code (DB2144code.exe), as well as the code text listing (DB2144code.txt), are available in the online version of this article at - Parallel-to-serial data conversion circuit

The listing uses the passed toggle_array values and returns two character codes, B and C, which would be forwarded onto the serial bus. The Partial Code Listing includes the algorithm that converts toggle_array bit values to the protocol needed by the SN74LV8153. The serial port defaults to Port 1 but may be respecified to Port 2 by asserting the Port Select toggle. It then displays the converted bytes in the text window and sequences them onto the RS-232 serial port and into the hardware shown in Figure 1. Clicking the graphic toggles the switch set, modifies the displayed graphic, and copies the Boolean setting to an array labeled as toggle_array(), as shown in the Partial Code Listing.Д¬licking the 'SEND' control box translates these stored values for D0 thru D7, and 3-bit device address, A0 thru A2, from the array into the 2-byte format required by the 74LV8153.

Pin 6, OUTSEL, is strapped for its active push-pull output configuration.ДЄ VB executable provides a toggle-switch graphic, text display, and send control box, plus the driver panel ( Fig. The output drives may be defined as open collector or as active push-pull. In this application, pins 2, 3, and 4 are strapped, corresponding to A0, A1, and A2 for device address 000. The 74LV8153 serial-to-parallel interface's protocol includes three address bits for selection of eight devices, providing up to 64 discrete outputs for each serial link.
