General purpose test modules to record and playback audio signals using Nuvoton's ISD series audio circuits (commercially known as ChipCorder). Presently, we have two modules for ISD1600 and ISD1700 series circuits which we offer costfree (as unmounted printed circuit boards without electronic components) with retail quantities of given type of ISD devices purchased from us. For each module, detailed documentation has been prepared, containing description of its construction, description of the functions realized by the audio circuits used in them along with method of realizing these functions. MART1600 with ISD1600 series integrated circuits (variable sampling frequency and recording bandwidth, variable record duration: 6.6 ... 40 sec) [PDF ]. MART1700_v2 with ISD1700 series integrated circuits (variable sampling frequency and recording bandwidth, variable record duration: 20 ... 480 sec) [PDF ]. MART1700_v2 module is the modified version of the previous MART1700 module [PDF ]. Both modules MART1600 and MART1700_v2 are so designed that they contain all the electro-mechanical elements (pushbuttons, switches and sockets) necessary for realizing individual functions of the audio circuits, and also have electret microphones forming the signal source for recording. They only require connecting up the supply source, external speaker and optionally an external audio signal source for recording. IPROG-1 Programmer for ISD4000/ISD5000/1700 series using Nuvoton's microcontroller [PDF] The programmer is used for programming sound devices of ISD4000/5000/1700 series with SPI interface when PC is used. Main features: records sound files, types *.wav and *.mid, to ISD devices, start and end addresses may be defined for each file, sound file tables may be defined and recorded, ISD memory scan function, a series of identical devices may be recorded, supports ISD4002, ISD4003, ISD4004, ISD5008, ISD5100 and ISD1700 device series as well as obsolete ISD33000 series, the programmer is interconnected between sound card and loudspeaker amplifier, no disconnection of audio lines is required even when programmer's power supply is turned off - PC sound is always audible, includes a built-in earphone amplifier, software compatible with WIN98/2000/XP. For programming of ISD1700 series additional adapter P1700/IPROG-1 is required, interacting with the programmer through its socket for programming of ISD5000 series. The program ISDProg v 2.86 [download ISDProg.exe (846k) or ISDProg.zip 383k] is used to handle the programmer. Winbond's Electrically Erasable EPROMs Eraser [PDF] Appliance used to erase Winbond's EPROMs. It facilitates application of these memories for users who have standard EPROM UV programmers without implemented function of Winbond EPROM erase. Basic features: ZIF socket with short-circuit and static electricity protections, automatic identification of the device type plugged into the socket, types of devices handled: W27E512, W27E010, W27E020, W27E040, verification if erasure was properly completed - "Blank Check" function, power supply: +9V, power supply unit comes with the Eraser, service mode available where user may, by himself, take all voltages existing at the ZIF socket. WinProg-1 Programmer for Nuvoton's 8-bit microcontrollers [download PDF doc] The programmer applicable to program Nuvoton's 8-bit microcontrollers, series W78... and W77... (except ISP devices). The programmer co-operates with any EPROM programmer and allows to download programs from EPROM (27C512) placed in ZIF28 socket to Flash ROM of the microcontroller under programming and located in ZIF40 socket. "Mart ISP" program to support in-system programming (ISP) of Nuvoton's microcontrollers [download MartISP (ZIP file 362k)] [download flash loader source code (.asm file)] The Mart ISP program is intended to operate in WIN95/98/2000/XP environments. It works with Nuvoton's ISP microcontrollers equipped with Marthel Loader. Microcontrollers are programmed via RS232 serial port. The in-system programming enables to avoid external programmer - all functions related to programming is included in Loader's code inside microcontroller. As compared with factory-made Loaders used at competitor's solutions, the Marthel's Loader enables to support, via ISP programming, external Watchdog connected to any microcontroller port. Automatic baud rate detection, invisible for the user, enables to use various frequency of microcontroller timing. The program features a convenient and simplified user's interface. In case of larger orders, the Loader's code may be customized. Currently, the ISP Loader is available for the following microcontrollers: W78E58B W78E858 W78LE58 W78E516 W78LE516 W77E516 W77E532 The main functions of the program are: Program - recording the program into microcontroller memory via the RS232 serial port. Verify - comparing the program in microcontroller flash memory with buffer contents. Erase - canceling the whole microcontroller flash memory. Blank check - verifying for the microcontroller flash memory is blank. Stop - stoping current operation. Run - restarting the CPU and to runing main program. Buffer edit - editing, filling in and canceling buffer contents
