RDA 5807 MODÜLÜ VE AT89S52 MİKROKONTROLCÜ İLE FM ALICI YAPIMI Bu projemde, piyasada bolca bulunan RDA5807 FM alıcı modülünün AT89S52 mikrokontrolcü ile kontrol edildiği bir FM Alıcı devresini paylaşıyorum. RDA5807 modülü, küçük boyutu, ucuz olması, kolay programlanabilmesi ve  RDS vb. özelliklerinden dolayı piyasada bolca bulunan ve hakkında internette sayısız kaynak olan favori bir radyo modülüdür. Genellikle Arduino ile programlama konusunda oldukça fazla kaynak ve bilgi olmasına karşın, AT89 serisi mikrokontrolcü ve Assembly dili ile kontrol edildiği bir kaynak bulamadım. Bu yüzden projeyi sıfırdan kendim yapmaya karar verdim. Resim 1. FM Alıcı devre şeması. Proje, devre şemasından görüldüğü üzere basitçe şu bileşenlerden oluşuyor:  AT89S52 mikrokontrolcü 16x2 seri LCD display modülü (Seri modül PCF 8574 çipli) RDA 5807 Radyo modülü  6 adet tact buton 11.0592 MHz (12 MHz de olabilir) Kristal 2x 22 pf kondansatör 1K direnç 10 uF kondansatör ÖNEMLİ UYARI!! Devrede önemle...

PROGRAMMING AN FM-AM RADIO TUNER USING THE LC72131 PLL IC Radio receivers made with LC72131 IC, and other members of this family, were frequently used in many Music systems, portable Radio - Cassette Players etc. devices in the 90s and 2000s. Thanks to the PLL frequency adjustment technique created using these ICs, it has been possible to make radio receivers that work stably. In this post, I will try to show how to tune an FM-AM receiver from such an old music system to the desired frequency (or station, as it can also be called). PURPOSE Tuning any FM-AM radio receiver using LC72131 IC, a member of the LC72xxx series PLL IC (integrated circuit) family produced by Sanyo, to the desired frequencies. WHAT IS REQUIRED A receiver circuit (Tuner stage) using LC72131 PLL IC. Audio frequency amplifier to connect the receiver circuit to the audio output. AT89S52 Microcontroller. Text editor required to program the microcontroller in Assembly language (Ex: Notepad ++) Asm51.exe .ASM to .HEX co...

FM RECEIVER PROJECT THROUGH RDA 5807 MODULE AND AT89S52 MICROCONTROLLER In this project, I am sharing an FM Receiver circuit where the RDA5807 FM receiver module, which is widely available in the market, is controlled by the AT89S52 microcontroller. The RDA5807 module is a favorite radio module that is widely available in the market and has countless resources on the internet due to its small size, cheapness, easy programming and RDS etc. features. Although there are many resources and information about programming with Arduino in general, I could not find a resource where it is controlled with the AT89 series microcontroller and Assembly language.  That's why I set out to do the project myself from scratch. Figure 1. FM Receiver circuit diagram. The project consists of the following components, as seen in the circuit diagram: AT89S52 microcontroller 16x2 serial LCD display module (Serial module PCF 8574 chip) RDA 5807 Radio module 6 tact buttons 11.0592 MHz (can also be 12 MHz) Cr...
